### Usage
165+

#include "stdlib/stats/base/dists/triangular/median.h"
168+
```
169+
170+
#### stdlib_base_dists_triangular_median( a, b, c )
171+
172+
Evaluates the [median][median] for a [triangular][triangular-distribution] distribution with parameters `a` (lower limit), `b` (upper limit) and `c` (mode).
173+
174+
```c
175+
double out = stdlib_base_dists_triangular_median( 0.0, 1.0, 0.8 );
176+
// returns ~0.632
177+
```
178+
179+
The function accepts the following arguments:
180+
181+
- **a**: `[in] double` lower limit.
182+
- **b**: `[in] double` upper limit.
183+
- **c**: `[in] double` mode.
184+
185+
```c
186+
double stdlib_base_dists_triangular_median( const double a, const double b, const double c );
187+
```
